BUILDING MATERIAL.

Application iled September 20, 1918. Serial lo. 255,005.

To all whom it may concern:

Be it known that I, WAmNrr Wawnzr- NIAK, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Building Materials, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to building materials and has for its object the production of a con lomerate plastic building material compose of several ingredients, and which when properly mixed and combined, affords an economical and eiiicient substitute for other forms of building material.

A further object is to provide a plastic building material which may be shaped to any desired form, and which will harden after being so shaped.

A further object is to provide such building material of a construction which will admit of the driving of nails, or the setting of screws into same without cracking the material, and `so that said nails or screws will be firmly held in place.

In the drawings, Fig. 1 is a sectional perspective of a conglomerate board, showing t e parallel reinforcing weed stalks;

F1g. 2, is a similar view of a conglomerate plank, showing double rows of weed stalks transversely disposed;

Fig. 3 is a similar view of a conglomerate block, showing a massed form of Weed stalk reinforcement.

In carrying out my invention, I utilize the ingredients and in the proportions as follows:

Cement-one part (bulk measure.)

' j u berfour parts (bulk measure.)

e liibred)two parts (bulk measure.

Weed stalks as a reinforcement.

e su s a'i'ce above referred to as Acme is 'an admixltur(n of calcium sulhate, more common own as gypsum, gfhose chemical formlslla is Ca an a brous substance, the latter constituting a strengthening and binding medium for the mass. Gypsum is found in its crystalline forms as selenite, anhydrite and alabastor. After the gypsum is calcined and reduced to a finely divlded mass it is i'ntermixed with a vegetable ber which gives additional strength to the plastic mass after setting. The mixture of calcined gypsum and the fiber is called Acme and is a product manufactured by the American Cement Plaster Co. of Lawrence, Kansas.

These ingredients are mixed together in their dry form. Water or other liquid is then added to reduce same to the desired consistency; that is to say, the consistency of a stiff mortar. This mixture is represented by 1 in the drawings. Thel reinforcing weed stalks, represented by 2 in the drawings, are then spread through the mixture spaced about one inch apart, or as may be desired. These weed stalks may be arranged parallel or crosswise as may be desired for any particular form of material.

mere this composition is to be used as a substitute for boards or planks, the plastic material 1 is spread out in a thin sheet, and the reinforcing weed stalks 2 are then laid down upon the plastic material in parallel lines, after which another la er of the plastic material is superimpose over the first layer to the required thickness, `thereby enclosing and encasing the weed stalks. When the material hardens, the result will be a com osite structure of the desired thickness, as s own in Fig. 1, and which will serve as a very etiicient buildin material, or as a substitute for boa-rds. plank or other thicker structure is best formed by superimposed layers of the lastic material 1 over transversely disposed ayers of weed stalks 2, as shown in Fig. 2. A block or other heavy structure may be best formed by promiscuously m'assing and intermingling the weed stalks 2 through the plastic material 1, as in Fig. 3. Likewise, the material ma be formed to any other suitable size for di ferent purposes required, and the reinforcing weed stalks may be interspersed accordlv. mvhile I have herein described a certain specific manner and method of assembling the elements of my invention, it is understood that I may vary from the same in minor-details, not departing from the spirit of my invention, so as to best serve the purposes intended, as defined in the ap'pended claims.

What I claim to be new and patentable is:

1. A conglomerate building material, comprising cement, Wood fiber, bered Acme, 3. A conglomerate building material, comweed stalks and a liquid mixed together to prising cement, wood ber, bered Acme, 10

the desired consistency. water and weed stalks, all intermingled to 2. A conglomerate building material, comform a plastic mass. 5 prising one part cement, four parts wood WALENTY WAWRZYNIAK.
